CHEM: Day 110 - Review notes for Radioactivity

Back when I first taught radioactivity to eighth graders, I put together some of the handouts you've seen and a couple of other notes for students. The "three day" timeline was a bit ambitious, but I've never changed the titles of the pages. This will give you some more written-up information and some extra stuff you might like to read about in preparation for your test on Friday.

Day One - Basic Stability and Nuclear Equation notes

Day Two - Zone of Stability, Predicting Decay, Decay Series and Half-Life

Day Three - Uses of Radioactive Isotopes, plus some notes on making Nuclear Weapons (NOT A MANUAL)

The Zone of Stability handout

Wikipedia notes on isotopes for fun

Average Atomic Mass presentation


Review topic list for the exam


Well, that should keep you busy.
